Application filed December 27, 1923. Serial No. 682,895.

This invention relates to an attachment for sewing machines intended forusev in sewing hook and eye holding tapes upon brassieres and othergarments of wearing I apparel, the present invention being a furtherdevelopment of one disclosed in Letters Patent of the United States No.1,524,013, dated January 27, 1925. V

In the said Letters Patenta'sewingmation is to provide a novelconstruction of means whereby the two presser feet and the two needlesof the machines which are adapted for simultaneously stitching the 5opposite-edges of hook and eye tape may be adjusted to adapt them foruse in connection with the said attachment in the sewing of hookand eyetape of different widths.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawing, and to the appended claims in which the Fig.is a face View of the needle holder. 1 Fig. '6 is a transverse sectionalview taken on the line 6-6 of Fig. 5. V

Fig. 10 is a similar view taken in the plane of'lines 1010 of Figs. 1.1and 12. Fig. 11 is a longitudinal central sectional view taken on theline 11'11 of Fig. 9.

Fig. 12 is a, transverse sectional view' taken, on the line 12-12 ofFig. 10.

Fig. 13 is a transverse sectional view taken on the line 13 1s'or Fig.10.

In Figs. 1, and 9 to 13, inclusive, of the drawing I have shown the hookand eye tape supporting and, guiding attachment by means of which thesaid tape is supported and guided through the machine in operativerelation to the work feeding and sewing mechanism which is illustratedin Figs. 1 to 8 inclusive. The hook and eye tape supporting and guidingattachment comprises a base or bottom portion 10 and atop plate 10 Thebottom plate 10 comprises a main or body portion, as clearly indicatedin Figs. 1, 9and 10,which is of substantially rectangular shape, andfrom the forward edge of which projects a tongue-like portion 10 fromthe opposite edges of the forward end portion of which projections 10extend. Bars 11 and 12 arranged in pairs as shown in the bottom plate10. The outer bars 12 are held in adjusted position by means of screws12*, the bottom end portions of which may be adjusted back and forth inslots 12. The

inner bars 11 are held in adjusted positions by means of screws 12,which may be ad justed back and forth in the slot 12 Mounted uponthe topsidesof the opposite edge portions of the rectangular shaped portion ofthe base member 1.0 are bars 12 which. are of rectangular shape in crosssection; These bars are held in place by the screws 12 Tape guidingplates 12 are mounted above the bars 12 and underneath the opposite'edgeportions of the top plate 10 of the attachment. The inner edges of theplate 12 are spaced from each other as clearly shown in Fig. 12 and areadjustable toward and from each other. plates, 12 are held in adjusted,clamped The said position between the top plate 10 and the bars 12 by.means of screws 12 which extend through elongated transversely extendingslots. .12 .in the said plates 12 The inner drawing are adjustablymounted upon the edge portions of the plates 12 extend part way over thetops of the bars 11 and 12, previously referred to. As will be apparentupon reference to Fig. 12 of the drawings the opposite edges of the tape12 are guided bythe inner opposing edges of the guide plates 12 In theemployment of the attachment not only may the guide plates 12 beadjusted to accommodate hook and eye tape of different widths, but thebars 11 and 12 may be adjusted. These adjustments will correspond to theadjustments of the presser feet, and needles, as will be describedhereinafter and are necessary in order that the said attachment maycooperate in an efficient and satisfactory manner with the sewingmechanism. I

Referring now to the presser foot construction, it will be noted thatthe presser foot bracket or holder comprises front and rear plates 15and 16 which are suitably spaced by the'bosses 17'and secured togetherby screws such as 18. Between these two plates the angular bars 20 andare located. These bars are guided in their adjustments by the bosses17, The presser feet .22 are hinged to said bars at 23. These bars 20and 21 are provided with threaded holes 25 which are engaged by headedscrews 26 which pass through horizontal slots 27 in the rear plate 16,the heads of the screws overlapping the slot. walls. As will beapparent, by loosening the screws, the bars 20, 21 can be adjustedtomove the respective presser feet toward and away from one another. Therear plate 16. is provided with a rearward and laterally extendingprojection 30 which is provided with an opening 31 whereby it may beattached to the presser bar. The presser feet 22, as will be understood,are positioned above the openings 13 and the feed dogs operatingtherein. For the purpose of engaging the tape midway between the presserfeet 22 and the said openings 13 I have provided a presserfoot element32 which depends from the front plate 15, with which, in theconstruction here shown, it is integral. 7 v

The needle holder comprises the rod 35 which is provided with a crossbar36 on its lower end. Upon this bar 36. is slidably positioned a pair ofbrackets 37 which are grooved on their rear faces to receive. said baras shownmost clearly in Fig. 6. These brackets are provided in theirlower portions with upwardly extending sockets to receive the upper endof the needles 38, whiehare fastened'in placeby set screws 39.

The brackets 37 are formed with longitudinal slots 10 of T-1form incross section through: which pass headed 41 which are threaded into.suitable. tapped holesv ad- :j aeent the opposite ends of the bar By e snin ese sets u flii issls d e b adjusted inwardly orioutwardly with theat the two needles at equal distance from the J median plane of thedevice. As here shown the bar 36 is formed with a longitudinal slot 45in which it positioned a gage block 46 which is stepped evenly from thecenter to the ends along one edge as at 47. Passing 3 freely through thebottom wall of the slot and threaded into a suitable socket in the block46 is a screw 18 which is held against axial displacement by a member d9engaging the head thereof. By rotating 2 this screw the block 46 can beprojected varying distances from the bottom of the slot 45. Theshoulders formed by the steps 1? operate as stops to limit the inwardadjustments of the needle holding parts 37. .1

The positionsof thefshoulders depend upon the position of the block 416with respect to the slot 45.

Having thus described my invention what I claim as new and desire toprotect by 1 Letters Patent of the United States is as follows.
